Over 84 percent of energy-related CO2 emissions from both the residential and commercial sectors was attributable to retail electricity. (Emissions from energy consumption for electricity generation are allocated to each sector in proportion to its share of retail sales.) The residential sector accounted for 19 percent of all carbon dioxide emissions from energy consumption; the commercial sector accounted for 18 percent.

The transportation sector accounted for 36 percent of total CO2 emissions from energy consumption, with 97 percent of the sector’s emissions attributable to petroleum; the industrial sector accounted for 28 percent of total emissions.

The MER provides monthly and annual data on total energy production, consumption, and trade; energy prices; overviews of petroleum, natural gas, coal, electricity, nuclear energy, renewable energy, and international petroleum; carbon dioxide emissions; and data unit conversions. See What’s New in the MER for a record of changes.
